No. I'm not even sure how that'd work, the charger can't tell the difference between batteries.

 

It's very, very detailed in what it can do, but if you want to track each battery you've got to do that yourself.

 

Given it's abilities though, it's not hard to discharge/charge a battery to get an idea of how "healthy" it is.  You can even just pop a NiHM in and it'll calculate its Internal Resistance. The higher it is, the more unhealthy the battery is.  High IR is what causes the crappy batteries to heat up when charging (you probably know this)

 

 

Smartphone camera. Then use the bluetooth to record the stats of the cell so I have an easier time getting equally good or crap ones.

 

Would be quite useful for those dick smith AAs I got where some are well over their listed capacity, which is the same for all of them despite clearly being different cells inside the DS label.

Oh right, yes, that'd be possible I guess.  The BT app really leaves a lot to be desired.  I mean, it works, but that's the nicest thing I can say about it.

Also that liitokala charger I got is pretty meh. Its test is just charging it and telling you what it puts in, has no discharge or conditioning options. Seems to really do an amp when set to it which is better than another charger I tried.

 

It also claims to report resistance, but every AA or AAA I put in comes up as 45. It varies on the 18650's somewhat but no idea how true it is.

I just keep batteries in sets. The C9000 tells me when they're duds, I tend to retire sets and use them for remotes and such. I have around 60 AA cells, for camera flashes and battery packs. I looked at NiMH D cells for my emergency LED lanterns, but they're pretty expensive, so I got a bunch of AA to D plastic shells so I can use my existing batteries in the lanterns.

 

 

I have a lot of very good new new condition Li batteries - pouch-type and 18650. I can load test them and sell if there is an interest..

That's what the friend of mine that I mentioned earlier did, he had a C9000 with some bad cells in a batch but couldn't figure out which ones. Turned out one was a dud, one was a bit flaky, and the others were fine, but you needed a charger that provided more info to see it.

 

 

Having said that, the Maha batteries are pretty good, I've had ancient, pre-LSD (or at least not advertised as LSD) ones last a year at a time in a clock.

Why couldn't he figure it out with a C9000? It shows information about every cell during the analysis or charging modes. The display cycles through each cell, clearly identifying which cell is a problem. When a cell is a problem the display tells you that.

 

I have non low-discharge batteries that are ten years old and still working just fine. I just make sure to refresh every six months and break-in maybe ever year or so.

Ah, sorry, wasn't a C9000 but one of the earlier models, the one that just has LEDs to indicate charge state.

The C801D is more basic, but still gives you some info, indicates bad cells. I like that I can charge 8 cells at a time, it has refresh cycle and slow option.

 @timmmay I'm looking at possibly getting the C9000 for charging AA batteries for a camera flash or two. Also looking at a C204U as a backup. Is the C9000 still the go-to, and from recharged.co.nz or ecobatteries.co.nz? Or should I look at the Nitecore D4? Will need to support 100V-240V for travel. Cheers and thanks!





Keep calm, and carry on posting.

Wow, I have a C9000 but had no idea I splashed out so much on one.  I got this when my DSLR camera worked on AA Batteries, but subsequent models have had proprietary battery packs.  I get the charger out every 6 months or so to refresh the remote eneloop batteries, and maybe my daughters point and shoot AA batteries.

 

 

 

It really is a marvellous bit of kit but I'm just hardly using mine anymore.  It's had a really easy life, but has worked wonders on my batteries.

I've only ever owned battery killers. Name brand stuff. Hopeless.

No idea about Nitecore but they're meant to be decent. My C9000 is probably over 10 years old and going strong, so it's highly recommended.

Thanks @timmmay, I'll sort one out from recharged or ecobatteries. Most appreciated.
